這篇文章將為大家詳細(xì)講解有關(guān)vue如何實現(xiàn)留言板todolist功能，小編覺得挺實用的，因此分享給大家做個參考，希望大家閱讀完這篇文章后可以有所收獲。
Vue是一款友好的、多用途且高性能的JavaScript框架，使用vue可以創(chuàng)建可維護(hù)性和可測試性更強的代碼庫，Vue允許可以將一個網(wǎng)頁分割成可復(fù)用的組件，每個組件都包含屬于自己的HTML、CSS、JavaScript，以用來渲染網(wǎng)頁中相應(yīng)的地方，所以越來越多的前端開發(fā)者使用vue。
第一步、使用bootstrap做好布局
<!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title></title> <link rel="stylesheet" href="lib/bootstrap.min.css"/> <script src="lib/jquery-1.7.2.js"></script> <script src="lib/bootstrap.js"></script> </head> <body> <div class="container"> <form role="form"> <div class="form-group"> <label for="username">用戶名:</label> <input type="text" id="username" class="form-control" placeholder="輸入用戶名"> </div> <div class="form-group"> <label for="age">年 齡:</label> <input type="text" id="age" class="form-control" placeholder="輸入年齡"> </div> <div class="form-group"> <input type="button" value="添加" class="btn btn-primary"> <input type="button" value="重置" class="btn btn-danger"> </div> </form> <hr> <table class="table table-bordered table-hover"> <caption class="h3 text-info">用戶信息表</caption> <tr class="text-danger"> <th class="text-center">序號</th> <th class="text-center">名字</th> <th class="text-center">年齡</th> <th class="text-center">操作</th> </tr> <tr class="text-center"> <td>1</td> <td>張三</td> <td>20</td> <td> <button class="btn btn-primary btn-sm">刪除</button> </td> </tr> <tr class="text-center"> <td>2</td> <td>李四</td> <td>22</td> <td> <button class="btn btn-primary btn-sm">刪除</button> </td> </tr> <tr> <td colspan="4" class="text-right"> <button class="btn btn-danger btn-sm">刪除全部</button> </td> </tr> <tr> <td colspan="4" class="text-center text-muted"> <p>暫無數(shù)據(jù)....</p> </td> </tr> </table> </div> </body> </html>
第二步、增加模態(tài)框，模態(tài)框默認(rèn)為隱藏的
<!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <title></title> <link rel="stylesheet" href="lib/bootstrap.min.css"/> <script src="lib/jquery-1.7.2.js"></script> <script src="lib/bootstrap.js"></script> </head> <body> <div class="container"> <form role="form"> <div class="form-group"> <label for="username">用戶名:</label> <input type="text" id="username" class="form-control" placeholder="輸入用戶名"> </div> <div class="form-group"> <label for="age">年 齡:</label> <input type="text" id="age" class="form-control" placeholder="輸入年齡"> </div> <div class="form-group"> <input type="button" value="添加" class="btn btn-primary"> <input type="button" value="重置" class="btn btn-danger"> </div> </form> <hr> <table class="table table-bordered table-hover"> <caption class="h3 text-info">用戶信息表</caption> <tr class="text-danger"> <th class="text-center">序號</th> <th class="text-center">名字</th> <th class="text-center">年齡</th> <th class="text-center">操作</th> </tr> <tr class="text-center"> <td>1</td> <td>張三</td> <td>20</td> <td> <button class="btn btn-primary btn-sm" data-toggle="modal" data-target="#layer">刪除</button> </td> </tr> <tr class="text-center"> <td>2</td> <td>李四</td> <td>22</td> <td> <button class="btn btn-primary btn-sm" data-toggle="modal" data-target="#layer">刪除</button> </td> </tr> <tr> <td colspan="4" class="text-right"> <button class="btn btn-danger btn-sm">刪除全部</button> </td> </tr> <tr> <td colspan="4" class="text-center text-muted"> <p>暫無數(shù)據(jù)....</p> </td> </tr> </table> <!--模態(tài)框 彈出框--> <div role="dialog" class="modal fade bs-example-modal-sm" id="layer"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal"> <span>×</span> </button> <h5 class="modal-title">確認(rèn)刪除么?</h5> </div> <div class="modal-body text-right"> <button data-dismiss="modal" class="btn btn-primary btn-sm">取消</button> <button data-dismiss="modal" class="btn btn-danger btn-sm">確認(rèn)</button> </div> </div> </div> </div> </div> </body> </html>
第三步、定義userList用來保存用戶，userName保存用戶名, age保存用戶變量， 然后把userName和age 通過 v-model指令綁定到對應(yīng)的輸入框，實現(xiàn)輸入框與變量中的數(shù)據(jù)雙向驅(qū)動，在表格的行中輸出userList
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">

<script src="lib/jquery-1.7.2.js"></script>

<script>
window.onload = function () {
var c = new Vue({
el: '#box',
data: {
userList: [],
userName : '',
age : ''
}
});
}
</script>
</head>
<body>
<div class="container" id="box">
<form role="form">
<div class="form-group">
<label for="username">用戶名:</label>
<input type="text" id="username" v-model="userName" class="form-control" placeholder="輸入用戶名">

<input type="text" id="age" v-model="age" class="form-control" placeholder="輸入年齡">

<div class="form-group">
<input type="button" value="添加" class="btn btn-primary">

<table class="table table-bordered table-hover">
<caption class="h3 text-info">用戶信息表</caption>
<tr class="text-danger">
<th class="text-center">序號</th>
<th class="text-center">名字</th>
<th class="text-center">年齡</th>
<th class="text-center">操作</th>
</tr>
<tr class="text-center" v-for="value in userList">
<td>{{$index+1}}</td>
<td>{{value.name}}</td>
<td>{{value.age}}</td>
<td>
<button class="btn btn-primary btn-sm" data-toggle="modal" data-target="#layer">刪除</button>
</td>
</tr>
<tr>
<td colspan="4" class="text-right">
<button class="btn btn-danger btn-sm">刪除全部</button>

<tr>
<td colspan="4" class="text-center text-muted">

<!--模態(tài)框 彈出框-->

<button data-dismiss="modal" class="btn btn-danger btn-sm">確認(rèn)</button>
</div>
</div>
</div>
</div>
</div>
</body>
</html>第四步、添加用戶，點擊添加按鈕，把輸入框中的數(shù)據(jù)作為一個對象 push 到數(shù)組userList，添加完之后，把userName, age清空，那么兩個輸入框的內(nèi)容就會被清空
